Creating a Pull Request from a Bamboo Plan

We have some plans ( both build and deploy) that do commit and pushes of branches. We would like to create a pull request automatically after a branch is pushed. Is there a quick way to do this? 

If we have to use Bitbucket APIs. Is there an example/documentation of how to use Python APIs for this purpose?

Thanks,

Hi @Subhi Andrews

You could use a script task and call a REST API to create the pull request.

Below you can find two examples using the curl command, one for Bitbucket cloud and another for server.


Bitbucket Cloud

 curl https://api.bitbucket.org/2.0/repositories/<USER_NAME>/<REPOSITORY>/pullrequests \
    -u <USER_NAME>:<APP_PASSWORD> \
    --request POST \
    --header 'Content-Type: application/json' \
    --data '{
        "title": "<PULL-REQUEST TITLE>",
        "description": "<PULL-REQUEST DESCRIPTION>",
        "source": {
            "branch": {
                "name": "<SOURCE_BRANCH>"
                }
            },
            "destination": {
                "branch": {
                    "name": "<DESTINATION_BRANCH>"
                }
            }
        }'

Reference: /repositories/{username}/{repo_slug}/pullrequests - Bitbucket API
⚠️Please make sure you create an app password with read/write permission for pull-requests.

Bitbucket server

curl <BITBUCKET_URL>/rest/api/1.0/projects/<PROJECT>/repos/<REPOSITORY-SLUG>/pull-requests \
    -u <USERNAME>:<PASSWORD> \
    --request POST \
    --header 'Content-Type: application/json' \
    --data '{
    "title": "<PULL-REQUEST TITLE>",
    "description": "<PULL-REQUEST DESCRIPTION>",
    "fromRef": {
        "id": "<SOURCE BRANCH>",
        "repository": {
            "slug": "<REPOSITORY_SLUG>",
            "project": {
                "key": "<PROJECT>"
            }
        }
    },
    "toRef": {
        "id": "<DESTINATION BRANCH>",
        "repository": {
            "slug": "<REPOSITORY SLUG>",
            "project": {
                "key": "<PROJECT>"
            }
        }
    }
}'

I hope that helps.

 

@Daniel Santos , Thanks. Could you also help us with APIs for merging the pull request?

We probably need to extract pull-request id from the creation of pull-request step.

Hi @Subhi Andrews

That should be the right direction.

  • Were you able to get it working?
  • Do you need it for Bitbucket cloud or server?

We were able to create Pull-Requests from Script task. Need an automatic merge from another script task or the same script task.

We use Bitbucket server

You will need to extract both the pull request ID version to merge it.

This is the call you can use:

Bitbucket server

curl -X POST <BITBUCKET_URL>/rest/api/1.0/projects/<PROJECT>/repos/<REPOSITORY_SLUG>/pull-requests/<PULL_REQUEST_ID>/merge?version=<VERSION> \
-u <USERNAME>:<PASSWORD> \
--header "Content-Type:application/json" \
--header "Accept:application/json"

Reference: /rest/api/1.0/projects/{projectKey}/repos/{repositorySlug}/pull-requests/{pullRequestId}/merge - Bitbucket Server REST API

Please keep us posted on your progres =]
